Free, open-source library for packet capture and network analysis on Windows, providing low-level network access for troubleshooting and analyzing network issues.

What is WinPcap?

WinPcap is an open-source library for packet capture and network analysis for the Win32 platforms. It provides a high-level and low-level API to capture and transmit network packets, giving developers direct access to packets traveling over the network.

Some key features of WinPcap include:

• Capturing raw packets, filtering them based on various criteria, and analyzing packet contents.
• Sending custom network packets.
• Support for both wireless and wired networks.
• Integration with Wireshark and other network tools.
• APIs for C/C++, Java, .NET, and MATLAB.

WinPcap is widely used in network tools and system utilities for debugging, troubleshooting, network monitoring, network forensics, and more. It allows developers to build packet sniffers, protocol analyzers, network monitors, and other software that requires low-level access to network frames. The library is open-source, well-documented, and has been under active development for over 15 years.
